File revision management

A computing device comprising:

• a network interface configured to communicate with a first endpoint device and a second endpoint device;
• a computer-readable medium;
• and
• a processing unit configured to store a file received from the first endpoint device in the computer-readable medium, store an updated version of the file received from the second endpoint device without overwriting an original version of the file as received from the first endpoint device,
• wherein, in response to receiving a request for the file from the first endpoint device, the processing unit is configured to send the original version of the file to the first endpoint device, and
• wherein, in response to receiving a request for the file from the second endpoint device, the processing unit is configured to send the updated version of the file to the second endpoint device.

A system comprising:

• a first endpoint device;
• a second endpoint device;
• and
• a director device configured to store a file received from the first endpoint device, store an updated version of the file received from a second endpoint device without overwriting an original version of the file as received from the first endpoint device,
• wherein when the first endpoint device requests the file, the director device is configured to send the original version of the file to the first endpoint device, and
• wherein when the second endpoint device requests the file, the director device is configured to send the updated version of the file to the second endpoint device.

A computer-readable storage medium encoded with instructions that cause a processor to:

• store a file received from a first endpoint device;
• store an updated version of the file received from a second endpoint device without overwriting an original version of the file as received from the first endpoint device;
• in response to receiving a request for the file from the first endpoint device, send the original version of the file to the first endpoint device;
• and
• in response to receiving a request for the file from the second endpoint device, send the updated version of the file to the second endpoint device.
